You can see the resemblance, can't you? This is a Megalopyge opercularis, or flannel moth caterpillar. It was spotted by photographer Jeff Cremer and biologist Phil Torres in the Peruvian rainforest. They look furry, and will become a fluffy moth as well, but don't touch it! Its "fur" is made up of venomous spines that can cause painful swelling that lasts for days. Link -via the Presurfer
